hyperid

Uber-fast unique id generation, for Node.js and the browser. Here are the benchmarks:

crypto.randomUUID x 12,969,725 ops/sec ±0.88% (91 runs sampled)
hashids process.hrtime x 419,350 ops/sec ±0.66% (94 runs sampled)
hashids counter x 819,049 ops/sec ±0.58% (93 runs sampled)
shortid x 40,820 ops/sec ±2.49% (87 runs sampled)
crypto.random x 372,773 ops/sec ±2.39% (84 runs sampled)
nid x 1,614,450 ops/sec ±0.38% (93 runs sampled)
uuid.v4 x 1,446,051 ops/sec ±0.60% (98 runs sampled)
napiRsUuid.v4 x 8,676,151 ops/sec ±0.49% (97 runs sampled)
uuid.v1 x 2,051,072 ops/sec ±0.15% (99 runs sampled)
nanoid x 4,293,733 ops/sec ±0.31% (97 runs sampled)
hyperid - variable length x 25,937,129 ops/sec ±1.48% (91 runs sampled)
hyperid - fixed length x 24,970,478 ops/sec ±1.48% (92 runs sampled)
hyperid - fixed length, url safe x 25,856,735 ops/sec ±1.93% (92 runs sampled)

Fastest is hyperid - variable length,hyperid - fixed length, url safe
Slowest is shortid

Note: Benchmark run with Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz and Node.js v22.0.0

As you can see the native crypto.randomUUID is almost as fast as hyperid on Node.js v16, but not on v14.

Install

npm i hyperid --save

Example

1'use strict'

4const instance = hyperid()
5
6const id = instance()
7
8console.log(id)
9console.log(instance())
10console.log(hyperid.decode(id))
11console.log(hyperid.decode(instance()))

API

hyperid([fixedLength || options])

Returns a function to generate unique ids. The function can accept one of the following parameters:

• fixedLength: Boolean If fixedLength is true the function will always generate an id that is 33 characters in length, by default fixedLength is false.
• options: Object If { fixedLength: true } is passed in, the function will always generate an id that is 33 characters in length, by default fixedLength is false. If { urlSafe: true } is passed in, the function will generate url safe ids according to RFC4648. If { startFrom: <int> } is passed in, the first counter will start from that number, which must be between 0 and 2147483647. Fractions are discarded, only the integer part matters. If { maxInt: <int> } is passed in, the uuid will be re-generated once the maxInt is reached. The lesser the maxInt, higher the performance because of SMI (a V8 optimization).

instance()

Returns an unique id.

instance.uuid

The uuid used to generate the ids, it will change over time. If maxInt is provided in options, then it will regenerated every maxInt, else it will be regenerated every Math.pow(2, 31) - 1 to keep the integer a SMI (a V8 optimization).

hyperid.decode(id, [options])

Decode the unique id into its two components, a uuid and a counter. If you are generating url safe ids, you must pass { urlSafe: true } as option. It returns:

1{
2  uuid: '049b7020-c787-41bf-a1d2-a97612c11418',
3  count: 1
4}

This is aliased as instance.decode.
